摘要：
A method of placing an implant including a stent at a native heart valve site includes orienting an expandable body of the stent such that a first open end of the stent is upstream a second open end of the stent relative to a direction of blood flow through a native heart valve. The native heart valve includes native leaflets and an annulus. The method also includes radially expanding a plurality of positioning arches positioned around an outer perimeter of the expandable body. The method additionally includes inserting the plurality of positioning arches respectively within a plurality of pockets defined by leaflets of the native heart valve and a heart structure from which the native leaflets extend. The method further includes radially expanding the first open end of the stent into a position upstream of the annulus and out of contact with nerve bundles.
